I asked Cezary to post those patches on alsa-devel to make sure there is no disagreement on the initial solution.

Both would be coming in early Q1 next year. _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
